The California written test covers traffic laws, road signs, and safe driving practices
California's written test for a driver license has 36 questions. You must answer at least 30 correctly to pass. The test covers California traffic laws, road signs, right-of-way rules, and safe driving practices. You take it on a computer at a Department of Motor Vehicles (DMV) office, and you get your score when ready after you finish.
The questions come from the California Driver Handbook, which the DMV publishes free online and in print. Every question on the test appears in that handbook or is based directly on information in it. You cannot pass by guessing — the test is designed to measure whether you understand the rules you will need to follow on the road.

What topics the test covers
The written test focuses on practical knowledge you need to drive safely and legally in California. The largest section covers right-of-way — who has the right to go first at intersections, when turning, and in other situations. You will see questions about what to do at stop signs, traffic lights, roundabouts, and when two vehicles reach an intersection at the same time.
Traffic signs make up another major section. You need to recognize common signs by their shape and color and know what they mean. Red signs mean stop or do not enter. Yellow signs warn of hazards ahead. White signs give information about lanes or parking. Green signs point to services or directions. The test shows you a sign and asks what it means, or describes a situation and asks which sign applies.
Safe driving practices are tested throughout. This includes speed limits (residential areas are usually 25 mph unless posted otherwise), following distance (at least three seconds behind the car ahead), how to handle skids or brake failure, and what to do if your brakes fail on a hill. You will also see questions about driving in rain, fog, or at night, and how alcohol and drugs affect your ability to drive.
Parking, lane changes, and turning rules make up another section. Questions cover where you can and cannot park, how to signal before turning or changing lanes, and what to do when merging onto a freeway. California-specific rules like the "Move Over" law (moving to another lane when passing emergency vehicles) appear on the test.
How the test is structured and timed
You sit at a computer terminal in a private testing booth at the DMV. The system presents one question at a time. You read the question and choose from four possible answers. You can go back and change your answer before you submit the test, but once you submit, you cannot change it.
There is no strict time limit per question, but the entire test usually takes 10 to 20 minutes depending on how quickly you read and decide. The computer does not rush you. If you need extra time because you read slowly or have a disability, you can request accommodations when you schedule your test or when you arrive at the DMV.
If you do not pass, you can retake the test the same day at most DMV offices, though you may have to wait and pay the test fee again. You can retake it as many times as you need, but you must pass before you can move on to the behind-the-wheel driving test.
Language and accessibility options
The test is available in multiple languages including Spanish, Mandarin, Vietnamese, Korean, Tagalog, and others. When you go to the DMV to take the test, tell the staff member which language you need, and the computer will display the test in that language. The system can also read questions aloud to you in English or your chosen language if you have difficulty reading.
If you are deaf, hard of hearing, or have a visual impairment, the DMV can provide an interpreter, large-print materials, or other accommodations. You should mention your needs when you schedule your test appointment, though you can also request them when you arrive. The DMV staff will work with you to make sure you can take the test fairly.
What you need to bring and what you cannot bring
You must bring a valid form of identification — a passport, state ID, or other government-issued ID with your photo and signature. You also need to bring your process paperwork if you have already submitted it, though the DMV can look up your information if you have an appointment scheduled.
You cannot bring study materials, notes, phones, cameras, or any other electronic devices into the testing room. You cannot bring another person with you into the booth. The DMV staff will lock up your belongings or ask you to leave them in your car. If you are caught with prohibited items, your test will be canceled and you may lose your test fee.
How to prepare using the California Driver Handbook
The California Driver Handbook is the official source for all test questions. You can read it free as a PDF from the DMV website at dmv.ca.gov, or you can pick up a printed copy at any DMV office. The handbook is organized by topic — traffic signs, right-of-way, speed limits, parking, and so on — so you can study the sections that are most important to you.
Read through the entire handbook at least once. Pay special attention to sections on right-of-way, traffic signs, and safe driving practices, since those topics appear most often on the test. After you read a section, try to explain the rules in your own words or imagine how you would handle the situation described. This helps you remember the information better than just reading passively.
Some people find it helpful to study with a friend or family member who can quiz them on the material. Others use the DMV's practice test, which is available online at dmv.ca.gov. The practice test has the same format as the real test and covers the same topics, so taking it gives you a sense of what to expect and shows you which areas you need to study more.
What happens after you pass
Once you pass the written test, the DMV will give you a receipt showing your score. You will then schedule an appointment for the behind-the-wheel driving test, where a DMV examiner watches you drive and evaluates your ability to handle the vehicle safely. You cannot take the driving test on the same day as the written test in most cases — you need to schedule it separately.
Between passing the written test and taking the driving test, you should practice driving with a licensed adult in the passenger seat. California law requires this for drivers under 18, but it is a good idea for anyone. The more time you spend behind the wheel before the driving test, the more confident and prepared you will be.
Frequently Asked Questions
Can I use the practice test to study instead of reading the handbook?
The practice test is useful for seeing the format and testing yourself, but you should read the handbook too. The practice test does not cover every topic as thoroughly as the handbook does, and reading the handbook helps you understand the "why" behind the rules, not just the answers to specific questions.
What if I fail the test — can I retake it right away?
Yes, you can retake the test the same day at most DMV offices. You will need to pay the test fee again and wait for an available testing booth. Some offices may have a short wait; others may be busy. Call your local DMV or check online to see how long the wait typically is.
Are the questions exactly the same every time, or do they change?
The questions change each time you take the test, but they all come from the same pool of questions based on the California Driver Handbook. This means if you study the handbook thoroughly, you will be prepared for any version of the test.
Do I need to pass the written test before I can get a learner's permit?
No. In California, you get a learner's permit first by passing the written test, then you practice driving with a licensed adult, and finally you take the behind-the-wheel test. The written test is the first step, not something you do after getting a permit.
What if I have a learning disability or read slowly?
Tell the DMV staff when you arrive, or mention it when you schedule your appointment. The DMV can provide extra time, read questions aloud, or offer other accommodations. You will not be penalized for using these services, and they do not affect how your test is scored.
